Retrofit2 encodes Query value even when encoded=true

Question

Using Retrofit 2.4, I'm calling an API that receives a JSON object as part of a query string such as /list?filter={"columns":"a,b,c","start":""...}

Instead of writing a converter I just use a jackson mapper to write the object as string before.

fun getReport(@Query("filter", encoded = true) request: String)

But what retrofit is doing is that it does not encode the brackets, but it does encode all the quotes, the url then becomes:

filter={%22columns%22: ...

And this is of course causing issues with the invocation.

Ideas?

Use QueryMap in your functions

@QueryMap(encodeNames = true)
